BACKGROUND: Cephalic index is an important factor of physical anthropology to find out racial differences in a particular area. Cephalic Index is expressed as %age of the breadth of head in relation to the length of the head. AIMS AND OBJECTIVES: To study cephalic index on tribals of Mewar in Rajasthan. MATERIALS & METHODS: This cephalometric study was carried out on 500 tribal subjects (269 male and 231 female) aged between 21 to 50 years, in Department of Anatomy, RNT Medical College, Udaipur, Rajasthan. RESULTS: Statistically significant difference (p<0.05) was found for head length, head breadth and cephalic index between tribal males 18.67±0.59, 13.76±0.52, 73.76±3.56 and tribal females 17.94±0.49, 13.34±0.37, 74.43 ±3.02 respectively and Dolicocephalic type of head was predominated. CONCLUSION: Sex determination and stature estimation becomes easier when standard Cephalic measurements of head for a specific population are available.
